How to implement usb touch driver in Wince 6.0?

Dear all:
I try to implement a usb touch driver in Wince 6.0, but I have some question as below:
1. What method do I use, usb client driver or touch driver?
2. Does any reference link?
I surved this link : https://msdn.microsoft.com/en-us/library/ee485627(v=winembedded.60).aspx
But I still have no ideal.
Thanks for your help, Victor

Definitely you need a USB client driver. Again what client class driver is required is depend on the USB touch screen module. Some vendors have a touch screen consist of one touch screen controller and a USB serial controller chip, the touch screen is exposed
as a USB serial client device though this you will read/configure the touch controller. In this case you need a USB serial driver to access this as a serial port and on the top you have to develop a touch driver as shown on the above link. It is all vendor
specific. Normally you need a bus to interface the touch controller. some touch screen controller are interface with I2C or SPI. Similarly here the bus is USB for your touch screen. So you need both driver, one is bus driver to access the touch controller
and another driver is to implement the touch functionality as shown in the above link.
First of all find the USB client class for your touch screen driver. you can contact the vendor or read the datasheet given by them.
Please mark as answer, if it is correct.
Please vote,if it is helpful post.

                Max Packet Size:   8
                Polling Interval:   10 ms
My test code source.
As the details, my infrared touch screen is not a HID USB device, and report interrupt input event. So, I need to write a custom USB driver for it. And then, I decided to write a USB driver kext.
According to the Mac Developer Library (I/O Kit Fundamentals),I see the Handling Events.To put the role of the work loop in perspective, it helps first to consider the event sources that it is designed for. In the I/O Kit there are five broad categories of asynchronous events:
Interrupt events—indirect (secondary) interrupts originating from devices
Timer events—events delivered periodically by timers, such as timeouts
I/O commands—I/O requests issued by driver clients to their providers
Power events—typically generated through calls down the driver stack
Structural events—typically events involving the I/O Registry
I set up their work loops, event sources, and event handlers in their start function.But not works.So, I can't get the data from USB touch screen device.
My questions:
Is there other ways to receive the report data from USB device in os x USB kext ?
How to dispatch the coordinate to system, when get the report data ?

How to mount USB & CDROM drives from single user mode - Solaris boot disk?

Hi All,
I need to carry out ufsrestore on a single newly replaced system disk (no redundancy / mirroring) from either USB or CDROM drives from the following steps:
( i ) GRUB => e, e, cdrom –s, Enter, b (boot from Solaris 10 x86 media).
( ii ) Choose menu 1 for Install Solaris Interactive Mode to reach single user mode.Below are the commands that I have tried in single user mode without success:
mount –r –F pcfs /dev/dsk/c1t0d0p0 /cdrom (after unmount Solaris CD)
mount: /dev/dsk/c1t0d0p0 is not a DOS filesystem.
svcadm –v enable smserver
svcadm: Pattern ‘smserver’ doesn’t match any instances
svcadm enable autofs
svcadm: Pattern ‘autofs’ doesn’t match any instances
devfsadm
devfsadm: mkdir failed for /dev 0s1ed: Read-only file system
mkdir /mnt
mkdir: Failed to make directory “/mnt”; Read-only file systemPart of the problem is due to the current READ ONLY filesystems which does not allow the creation of mount point such as /mnt.
I have been able to create both / root (/dev/dsk/c1t0d0s0) and /export/home (/dev/dsk/c1t0d0s0) filesystems with newfs that are awaiting for restore using ufsrestore.
The only option I am left with is to attach a secondary disk to install Solaris 10 on either of them before bring the system to multi-user mode so that service such as volmgt, autofs, volfs are available to access USB & CDROM drives.
Any suggestion on how to resolve this issue?
Many thanks,
Jack

Hi JKGN,
Is the directory a located under the root filesystem. ie /a? Are there any other mount point for say USB drive as well? I am not in a position to try it out right now but will get back
to you soon on whether /a exist or not.
Btw, the last thing I managed to do on this system at the time was added a secondary 1TB internal disk with the intention to restore both / and /export/home data onto this disk while
making use of all the disk device management services such as the following services only available in a fully installed Solaris system (both single & multi-user modes) installed on the
primary disk:
# svcs smserver
STATE          STIME    FMRI
online         Jun_08   svc:/network/rpc/smserver:default
# svcs autofs
STATE          STIME    FMRI
online         Jun_08   svc:/system/filesystem/autofs:default

        Device Type: DVD Reader/WriterHowever, I was disappointed that "iostat -En" has not found the secondary disk (1 TB) even though it was available earlier, for Solaris installation as the only disk on the same system.
As a result, I am left with no option but the need to rebuild this system with only a single primary disk while in single user mode. However, the single user mode that I am in is the
one from Solaris installation disk with restrictive (_cannot create folder for mount point or running disk management utilities_) capability such as those services just covered, compared to one from a completed Solaris installation system with full access to all filesystems and utilities / commands in general.
I would very much value your assistance on how to mount both CD & USB in this restrictive limited Read Only OS (assume that it is running from memory) in order to get complete access to
the blank primary disk so that full restore with ufsrestore could take place.
Thanks in advance,
Jack

How to use usb flash drive

So i tried to use a usb flash drive to save a word document on my macbook, but i couldnt find the flash drive, or even where to find the usb port. can somebody tell me how to use a usb flash drive on macbooks?

The USB ports are on the left side.
Just plug in the drive, and it should show up on your desktop (or in the Finder - click the happy face icon in your dock). Drag and drop the files into the drive. Or, select the drive as the save location when you pick Save or Save As in Word.
When you're done, drag the drive's icon to the trash (it will change to an eject symbol), or click the little eject symbol next to it's icon in the Finder. You can then safely unplug the drive.

How to mount USB Flash Drive

Hello again Arch-Linux users,
I always search google very hard and for months (off and on) I search for how to mount a USB Flash Drive. Nothing ever work so I give up than try again months latter. I don't want to give up anymore and that is why I join this forum.
Here are some of the code I found on the net. Some of these commands will only re-mount the entire Arch-Linux running system in /mnt/usbstick.
sudo mount -o rw,noauto,async,user,umask=1000 /dev/sda1 /mnt/usbstick
... don't work it only re-mount the entire system
/dev/sda15 /mnt/usbstick vfat user,noauto,unhide 0 0
... don't work... I found nothing inside /mnt/usbstick
mount -t vfat -o rw,nosuid,nodev,quiet,shortname=mixed,uid=1001,gid=100,umask=077,iocharset=utf8 /dev/sda1 /mnt/usbstick
... don't work... here is the error i get:
mount: /dev/sda1 already mounted or /mnt/usbstick busy
mount: according to mtab, /dev/sda1 is mounted on /
It strange that most USB mount commands use the operating system partition itself- example: /dev/sda1 as the device for USB device, while others use /dev/cdrom for cd - /dev/dvd for dvd and /dev/fd0 for floppy.
Could someone post the code that will easily mount a usb device under Arch_Linux.
I'm using Arch-Linux core-64 (08-2009)
Thanks in advance

Thanks fsckd,
I needed a rapid reply because I been wasting too much time not getting anything done because I needed to get pass this flash-drive thing. I can now have a secure back-up in my pocket on USB to go. Arch-Linux does it better for what I seen while just dd'ing on disk.
...lsusb
Found it

Thanks demian,
sdb is the location for my single hard-drive machine. I saw it before in my list above but I changed it to sda1 because I knew no better. I had no clue it represent a 2nd hard-drive for LINUX if one is not already present.
This did it for me
Thanks again

How to detect USB Flash Drive name in LabVIEW

Hi there

appearently every time i insert USB Flash Drive in a computer, windows assign it a different name
once "J:" and sometimes "M:"
Is there anyway to obtain USB Flash Drive name programmatically in Labview ?
Because in my program an user shouldn't be able to access HDD Drives except his USB Flash Drive (for inserting some file ...)
thank you and excuse me for my poor english

I was able to get the demo.vi to load, but it could not load the other two because there is no block diagram associated with those. I'm not sure why this is. I haven't had any issues with other llbs before.

How to made usb pen drive a recovery tool....?, how to made usb pen drive a recovery tool....?

As I have downloaded your Recovery Assistant tool on Intel base machine now please describe the whole process to make USB pen drive a recovering tool for my Mac Book Pro as it was pre-install a Snow Lapord OS X.

What OS are you trying to make a bootable recovery for?
10.6 is not available for download and I can't see how you have a MacBook Pro with Retina that came with 10.6.8?
You can either make a recovery disk (which boots & then downloads the installer from the App store). clintonfrombirmingham linked instructions for that.
Or you can make a bootable install disk. First you download the OS from the App store & then use a command to image the installer to a USB disk.

10.6 should be on a DVD installer disk which can be copied to a USB disk via another method, ask if you need that.

How to use usb super drive at mcbook pro with retina

I had just bought a mcbookpro with retina on-line. I bought a USB super drive as well. I don't know how what button i'll be using to operate the usb super drive. Can anyone help?

If you've a CD with Microsoft Office on it, all you need to do is double-click the installer program on the CD. If you don't see the CD mounted on your Desktop, go to Finder>Preferences>General, and tick the box that says "CDs, DVDs, and iPods" under "Show these items on the desktop".
After you've finished installing Office, simply drag the disc to the Trash and it will eject (I don't have a Retina display model, so I'm not sure if there's an optical disc eject button next to the F12 key or nor - if there is, you can use that as well).
Hope this helps.

How to format USB flash drive?

I recently received a USB flash drive at a traveling covention. It has two partitions and one is unwritable and is filled with travel brochurs etc etc. I was wondering if it was possible to reformat the whole thing back into 1 partition. I already tried disk utility. Thanks!

Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
